- sent however the inconvenience that the filing holes in thenewspapers, books of music or the like, tear out easily or get wider atrepeated use so that the filed papers get loose. To obviate thisinconvenience it has been proposed to reinforce the paper edge or toi'nsertin the fold of the book a. wire, a strip of fabric or the like;These precautions are not only trouble'some and expensive but they donot prevent the books from getting loose as they cannot be maintained inthe files.

It has further been proposed to provide on the inner surface of the backof the file at the filing points clamping springs on the one handdesigned to securely hold the filed newspapers or books and on the otherhand carrying pins engaging with the perforations of the filednewspapers, book or sheets. These pins are hingedly connected to theclamping springs and telescoped the one into the other, a special keybeing required for opening the filing pins. This inconvenience is due tothe fact that the ends of the clamping springs are not accessible buthidden in the file back and situated underneath the edges of the coverback so that these files are not easy to manipulate and ratherexpensive.

All the above mentioned inconveniences are obviated by the presentinvention, according to which holding means for the filing pins arearranged on the back of tee file at the leafimpaling points, saidholding means projecting over the edges of the cover and beingcontrolled by resilient or elastic elements so that they strongly presstogether the filed sheets or hooks at the filing points.

These means for holding the filing pins may be of various constructions;they may consist As filing pins narrow or flat metal strips. 7preferably of spring steel, are used.

Several embodiments of the invention are illustrated by way of examplein the accompanying drawings in which Fig. 1 shows an open file in frontelevation;

Fig. 2 shows on larger scale a cross-section through the open file. v

Referring to Figs. 1 to 6 clamping springs 2 in the form of fiat stripseach bent so that its" ends are adjacent to each other are inserted inthe back of the file 1. One of the 803?:

two ends of the clamping spring has an ex- After the periodicals havebeen filed on the filing pin 5, this pin can be inserted in the hook 4Land its free end inserted into the open end of the pocket 7 ofthe cover.The rear' end of the filing pin can be fiXed in the'left cover of thefile, or both ends of the pin may be inserted into pockets 7 of thecover as shown in Figs. 11 and 14.

The perforations in the first and last sheets,

periodicalsand the like which have been filed the applica 711"} I cannotbe widened by the filing pins, as the ends of the clamping springsforming the holding means for the filing pins project over the edges ofthe cover back and form a frame around the perforations.

Referring to Fig. '7 the pin-holding means consists of latches 8 in theends of the clamping spring 2. As shown in Fig. 7 the ends of theclamping springs 2 are bent over so that they form a guide for thelatches 8. The latches 8 are arranged longitudinally shiftable and holdthe pins 5 tightly in that they grip over their arms (Fig. 9). Fig. 9shows in top plan View a file 1 fitted with this fileholding means.

Figs. 8, 10, and 11 show claws 9 in the ends of the clamping spring,said claws designed to engage with corresponding depressions 10 of bars11 Each bar 11 as shown in Figs. 10, 12 and 13 is of thin flexiblematerial and preferably stuck on a sheet 12. A separate sheet 12 with athin metal bar is preferably arranged on the inner surface of thecorrespending cover in all the different forms of holding means for thefiling pins, in order to preserve intact the first and last sheets 01':the papers filed.

I claim 1. A file for holding the papers, books and the like to befiled, the pile of filed papers being compressed at the filing points,comprising in combination with the file back, the filing pins andclamping springs inserted in the file back at the leaf-impaling pointsso' that their ends project over the edges of the file back, said endsof said clamping springs constructed to form holding means for saidfiling pins.

2. A file for holding the papers, books and the like to be filed, thepile of filed papers being compressed at the filing points, comprisingin combination with the file back, the filing pins and clamping springsinserted in the file back at the leaf-impaling points so that their endsproject over the edges of the file back, said ends of said clampingsprings constructed to form holding means for the filing pins, saidholding means covering frame-like the perforations in file papers.

1 3. A file for holding the papers, books and the like to be filed, thepile of filed papers being compressed at the filing points, comprisingin combination with the file back, the filing pins and clamping springsinserted in the file back at the leaf-impaling points, an

extension on each end of each of said clamping springs, projecting overthe edges of the file back, one of said extensions having an eye and theother of said extensions having a slot adapted to engage in said eye toform holding means for said filing pins.

4. A file for holding the papers, books and the like to be filed, thepile of filed papers being compressed at the filing points, comprisingin combination with the file back, the

prising in combination with the file back, the r filing pins andclamping springs inserted in the file back at the leaf-impaling pointsso that their ends project over the edges of the file back, latches inthe ends of said clamping springs adapted to form holding means for saidling pins.

6. A file (with filing pins) for holding the papers, books and the liketo be filed, the pile of filed papers being compressed at the filingpoints, comprising in combination filing pins, claw-like clampingsprings inserted in; the file back at the filing points so that theirends project over the edges of the file back,

said ends of said clamping springs constructed to form holding means forsaid fil ing pins, separate sheets on the inner surface of the twocovers, and a cover bar on each separate sheet having depressionsadapted to receive said claw-like holding means.

In testimony whereof alfix my signature.
